JOHN JAS. SETTER, OF POPLAR POINT, CANADA.

MACHINE FOR BURNING SEEDS OF NOXIOUS WEEDS.

SPECIFICATION forming part of Letters Patent No. 610,612, dated September 13, 1898.. Application filed December 22,1897. seem No. 663,094. (No model.)

T0 whom it may concern:

Be it known that 1, JOHN JAMES SETTER, of Poplar Point, in the county of Marquette and Province of Manitoba, Canada, have invented a certain new and useful Machine for Burning the Seeds of Noxious Weeds; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a machine by means of which the seeds of noxious weeds may be destroyed either whileon the plant or when lying exposed on the surface of the ground; and theobject of the invention is to so construct the machine that it will be easily transportable and will throw a jet of flame over a comparatively wide tract of land; to so arrange the several parts constituting the machine that the jet of fiame will be confined entirely within its boundaries; to so arrange the burners of the machine that the flame can be directed upon the surface of the ground over which it is traveling, and to provide the machine with a blower to forcibly direct the flame to the surface; and the invention consists, essentially, of a machine comprising a frame supported by the usual carrying-wheels and fitted with a draft-tongue, a fire-box suspended from the frame, a blower mounted on the top of the frame having any predetermined number of wind-trunks and windspreaders within the firebox, a burner opposed to each wind-spreader, a valve-controlled fnel-supply tank in connection with the burners, means for driving the blower from the carrying-wheels, a pivoted front and a pivoted back for the fire-box,'colters or cutting-disks opposed to thefront of the sides of the fire-box, and a harrow coupled to the back of the machine, as hereinafter set forth, and more particularly pointed out in the claims.

In the drawings, Figure 1 represents a perspective view of the machine, looking at it from the top. Fig. 2 is a similar view showing the wind-trunks,wind-spreaders, and burners.

Like letters of reference refer to like parts throughout the specification and drawings.

A represents the main frame of the machine, embracing in its construction two opposite and parallel sides Ct a and ends I) b, rigidly joined in the usual manner.

B 13 represent the hounds connected to the front of the frame A and carrying one part of the fifth-wheel C, while the other part of the fifth-wheel C is carried by the axle D of the front carrying-wheels E and connected to the hounds by a king-bolt. Oonnectedto the axle D isa draft-tongue F.

G G represent two brackets connected one to each side of the frame A, contiguous to the rear end. H represents the axle of the rear carrying Wheels mounted in the brackets G G, and I I represent the rear carrying-wheels mounted on the ends of the axle H.

J represents a cross-shaft j ournaled in bearings connected to the sides a a at substantially the middle of the frame A. Loosely mounted upon the shaft J at one side of the frame A is a sprocket-wheel K, and rigidly mounted on the axle H at the same side of the frame A is a sprocket-wheel L. Passing around the sprocket-wheels K L is a sprockeo chain M, by means of which motion is transmitted from the sprocketwheel L to the sprocket-wheel K. Slidingly mounted on the shaft J and revolving therewith is a clutch member N, which is adapted to mesh with a corresponding clutch member on the side face of the sprocket-wheel K. 0 represents a lever for throwing the slid ing clutch member N into or out of engagement with the clutch member of the sprocketwheel- K. I hen the clutch member N is meshing with the clutch member of the sprocket-wheel K, the shaft J is caused to revolve with the sprocket-wheel K, when the sprocket-wheel has motion imparted to it from the carrying-wheels by means of the sprocketchain M during the progress of the machine. Itigidly mounted on the shaft J, on the oppo site side of the frame A to the sprocket-wheel K, is a pulley P. Mounted in bearings Q Q, connected to the side bars a a of the frame A, is the fanner-shaft R of the blower. Rigidly mounted on the middle of the fannershaft R is the fan S, which is contained within a casing T, provided with two wind-trunks U and V, respectively, arranged diametrically opposite to each other on opposite sides of the vertical axis of the fanner-shaft.

W represents a fire-box suspended from the under side of the frame A and located be top 0, is a damper e.

tween the carrying-wheels II. The fire-box W consists of a top 0 and two opposite sides d at, extending downwardly from the top 0. Pivoted to the front of the sides d d, contiguous to the top 0, is a damper e, and pivoted to the rear of the sides dd, contiguous to the The top 0 with the sides 01 d and dampers ee form a practically-closed fire-box to confine within it the flame. The object of pivoting the dampers cc to the sides is to permit them to yield to the irregularities of the surface over which the machine is moving. The wind-trunks U V extend through the top a into the body of the fire-box WV. The wind-trunk U is provided with a windspreader U, while the Wind-trunk V is provided with a wind-spreader V. The windspreaders U V are within the fire-box W,and opposed to the mouth. of the wind-spreader U is a burner X, while opposed to the mouth of the wind-spreader V is a burner X. Oonnected to the burn er X is a feed-pipe E, leading to a fuel-reservoir F, held in swing-racks F, connected to the sides of the frame A, while connected to the burner X is a feedpipe E, which also leads to the fuel-reservoir F. Each burner consists of a pipe having any required number of rearwardly-projecting jets arranged at regular intervals along it. The burners X X are placed to the rear of their respective Wind-spreaders U V.

Within the fire-box W are two fire-pots W W, which are arranged in to the burners X X, respectively. Each of the fire-pots embraces in its construction a front to, connected to the inner side of the top of the fire-box'and opposed to the front of its respective burner, and a series of substantially V- shaped grate-bars projecting rearwardly from the bottom of the front and below the burner.

Connected to the front of each of the sides cl d is a bracket G, and journaled in each of the brackets G is a colter or cutting-disk H, each of which is in alinement with its respective side (1 of the fire-box, The purpose of the colters H is to cut a furrow for its respective side 61 of the fire-box, in order that the side can enter the furrow and contain within the fire-box the flame thrown upon the ground from the burners. Connected to the side of the frame Ais a harrow I.

The operation of the device is as follows: The horses or other motive power is applied to the draft-tongue F and causes the forward progress of the machine. The forward progress of the machine causes the revolution of the rear carrying-wheels I I and axle H. The revolution of the axle H causes the revolu tion of the sprocket-wheel L, which imparts a revolutionary motion to the sprocket-wheel K through the agency of the sprocket-chain When the clutch member N is in mesh with the clutch member of the sprocket-wheel K, a rotary motion is imparted to the shaft J and pulley P, which imparts a rotary motion to the pulley K, mounted on the end of close proximity.

the tanner-shaft B, through the agency of a belt K, passing around the pulleys P K. The revolution of the pulley K causes the revolution of the fanner-shaft R and fan S. The revolution of the fan S creates a current of air and forces it through the Wind-trunks U and V to the respective wind-spreaders U and V. The fuel being ignited in the firepots is fanned into a flame, which is forced upon the ground by the distribution of the wind from the mouths of the Wind-spreaders U V. The sides cl d and dampers e e of the fire-box W confine the fire within the fire-box and prevent it igniting any combustible material on the outer side of the machine. The dampers e e or ends of the fire-box, being pi voted, readily pass over any inequalities in the surface of the ground over which the machine is traveling, and the end damper e assists in extinguishing the flame of the material burning within the fire-box during the progress of the machine. To more effectually extinguish the flame, the harrow I is connected to the rear of the frame A. By providing the colters at the front of the fire-box and arranging these colters so that they are opposite to the ends of the sides cl d a furrow is cut for each side, into which it may enter during the progress and operation of the machine. By providing these furrows the fire is more effectually contained within the fire-box, and any danger of igniting any material on the outer side of the fire-box is completely avoided. When it is necessary to intensify the flame, the fuel of the burners is ignited and forced to the ground with the flame from the fire-pots.

I do not confine myself to the use of any particular fuel for producing the consumingflame, as I may use any class of animal, Vegetable, or mineral oils or any of the solid fuels; nor do I confine myself to any particular style of burner, nor to any particular shape or size of the parts, as I may use any style of a frame, fire-box, and blower suitable for the purpose. Neither do I confine myself to any particular style of full reservoir, nor to any particular means of connecting it to the frame of the machine.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
